Title: Oil returning device for compressor
Inventor: OZAWA HITOSHI
IPC: F04C29/02
Filed: 1986-12-28
Abstract: PURPOSE:To simply form an oil return passage without the occurrence of refuse clogging by forming a recess on the opening side of a bush toward an inner chamber on a high pressure side, and protruding a capillary tube deeply from the hush into the recess. CONSTITUTION:Oil having entered an inner chamber 1a on a high pressure side is once stored in a recess 9, and then returns through the inside of a capillary tube 8 from the recess 9 into an inner chamber 1b on a low pressure side. In this case, since the capillary tube 8 is positioned with its upper end protruding deeply from a bush 7 into the recess 9, the oil whose refuse or the like has been depositedly removed in the recess 9 is supplied from the upper end of the capillary tube 8, resulting no refuse clogging in the capollary tube 8. In addition to that, in fitting the capillary tube 8, a through hole 6 having a large diameter is formed through an isolating member between a high pressure and low pressure side to insertedly support the capillary tube 8 through the bush 7. An oil return passage can be therefore simply formed without any technical difficulty.

Title: Picture scanning device
Inventor: MORIKAWA TAKESHI
IPC: G03G21/00
Filed: 1988-12-13
Abstract: PURPOSE:To attain speed control without storing a control pattern by calculating acceleration at the time of energizing and acceleration at the time of non- energizing at a prescribed time point and determining a parameter executing the speed control of a scanning system based on this acceleration. CONSTITUTION:A signal MAG given to an input port 45 shows a copying magnification selected in a copying machine and in a microcomputer 41, scanning speed is set in correspondence to the magnification. When object speed is attained, by the microcomputer 41, it is judged from the interval of an encoder pulse (e) at that time that the object speed is attained. Based on this judgement, the control of a motor 30 is switched to the control of constant speed scanning. In this control, the PWM pulse of a PWM output port 47 is defined as a motor energizing pulse (d) and the constant speed control of the motor 30 is executed. However, when the object speed is attained, the acceleration at the time of energizing and the acceleration at the time of non-energizing are calculated. After that, these two types of the acceleration are defined as the parameter and the duty of the pulse (d) is rewritten at every pulse (e). Thus, in correspondence to the loading torque of the scanning system at such a time point, the scanning speed can be set suitable.

Title: Production of micromachine
Inventor: SUMI HIROBUMI
IPC: H01J9/02
Filed: 1992-10-30
Abstract: PURPOSE:To provide the micromachine capable of executing fine working of a high degree by using an etching gas for forming chemical species of a halogen system and free sulfur and etching a base body consisting of a silicon material while depositing the sulfur. CONSTITUTION:Resist patterns 2 are formed on a base body 1 to be etched and this base body is set on the stage of a microwave plasma etching device. The base body is kept at about <=-70 deg.C and is etched by using gaseous S2F2. The F radicals dissociated and formed from the gaseous S2F2 act as etching species and the etching of the base body 1 progresses. The S released into the plasma at this time deposits on the side wall surfaces of the base body 1 which is kept cooled, by which protective films 3 for the side walls are formed and, therefore, the etching of the base body 1 progresses only in its depth direction. The protective films 3 and the patterns 2 are then removed and thereafter an oxidized film (SiO2)4 is formed over the entire surface of the base body 1. A laminate 5 consisting of polycrystalline silicon is deposited on this oxidized film 4 by using a gaseous mixture composed of SiH4/He/N2.

Title: Blower control method for air conditioner
Inventor: AKAO MINA
IPC: F24F11/04
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To perform efficient operation of an air conditioner and a blower by a method wherein when the output of an air speed detecting means is increased to a value higher than some specified set value during operation of the blower, the blower is stopped. SOLUTION: During running of the blower of the outdoor machine of an air conditioner, an air speed is detected by an air speed detecting means 3 mounted in the vicinity of a heat exchanger 2. When a value of a detecting air speed is below some specified set value, ordinary operation is effected. However, when the detecting air speed is increased to a value higher than some specified set value, it is decided that strong wind flows and since sufficient heat-exchange by natural wind is carried out, a blower 1 is stopped. This constitution reduces a consumption power of an outdoor machine.

Abstract: PURPOSE:To have sensing with high sensitivity and high reliability without generating Q-damp in a tuning circuit by changing the output frequency of an oscillator circuit by a variable capacity diode while following-up after the resonance frequency of the tuning circuit which is displaced by unnecessary factors. CONSTITUTION:An oscillator circuit 1 has a built-in ceramic resonator 10, and an oscillative frequency signal is fed to a tuning circuit 2, which has a ceramic resonator 12 and changes the tuning point with the signal while receiving change of the external electrostatic capacitance. An automatic frequency control circuit 6 equipped with a variable capacity diode changes capacity with unnecessary signals included in the output signal of the tuning circuit 2 and displaces the oscillative frequency of the oscillator circuit 1 in following-up after the resonance frequency of the tuning circuit 2 which is displaced by unnecessary factors. Thus a change in the tuning point resulting from environmental change etc. is corrected without generating Q-damp in the tuning circuit 2 by stabilizing the tuning point in the manner as described, and now the change of the electrostatic capacitance can be sensed always with high sensitivity and high reliability.
